Answer 1

Explicație pas cu pas:

$12.4(04) = \frac{12404 - 124}{990} = \frac{12280^{(10} }{990} = \frac{1228}{99}$

$- 1.2(31) = - \frac{1231 - 12}{990} = - \frac{1219}{990}$

$0.23(1) = \frac{231 - 23}{900} = \frac{208^{(4} }{900} = \frac{52}{225}$

$- 2.3(01) = - \frac{2301 - 23}{990} = - \frac{2278^{(2} }{990} = - \frac{1139}{495}$

$0.23(14) = \frac{2314 - 23}{9900} = \frac{2291}{9900}$

$1.23(145) = \frac{123145 - 123}{99900} = \frac{123022 ^{(2} }{99900} = \frac{61511}{49950}$
